The present invention relates to .driving means for'toy vvehicles or the like, an ob]ectV of this invention being' to provide a construction in whicha speed'increasing gearingis employed in suchy a manner that upon thewinding of the spring through thepropelling wheel, said gearing. is effective. Another object of the invention is to -piovide a construction whichs o f compact form so thatit may be readily housed iny a-wheel Vand anaxle of the toy. Still anotherkob- #ject ofthe invention is to .,providel an iinprovedfmeansof interposing a speed 1ncreasing mechanism or gearing between propelling wheel of a vehicley anda motorA driven member. f

To these and other ends, the invention con sists of. certain parts and combinations of parts, all of which willrbe 'hereinafter described, the novel features being pointed out in the appendedclairns. Y "In the drawings: v n "Fig 1 is a sidevew of a toy constructed inaccordance with tliis'invention;

Fig. 2 is a longitudinal section through the rear wheels` and lan. axle .of the toyvehicle;

Fig. 3 is a section on the line 3-3, 2;

4. is a section onthe lineV -JLFig. 2; Fig. l5 is a section on'the line 5-'5, Fig. 2;. Fig. 6 is a section on the line (ie-6, Fig. 2; and i l f Fig. 7 is a fragmentary sectional view of another embodiment of the invention;

y Referring to the embodiment of the invention illustrated in Figs. 1 to 6, 1 indicates a figure toy vehicle such as a bear-,which has a'front axle 2 on'whicli wheels 3 turn. A rear axle 4 connects the rear legs and is,v in this instance, in thevform of a stationary tube held'against turning on the legs. .In this tube is mounted a. helical spring 5 which at one end 6 is secured to the tubular axle, the other end being secured to a spring rotated or motor driven member 7 also in the form of a tube, spaced from the tube 4 to provide a chamber for the spring 5, the

spring being secured at 8 to this inner tube or spring rotating member. Extending through the tube 7 is a shaft 9 ywhich has two wheels 10 and 11 rigidly secured to opposite ends thereof. In this instance', an internal cup shaped hub 12 is provided on the wheel 11 and thesh'aft 9 is formed with a noncircular portion "13 extending through this hub and the outer wall of thelwheel, 'the wheel being 'confined between theV upset porsleeve.

tion 1,4 on the outer end of the non-circular portion and a shoulder 15 at the inner end of the non-circular portion. A disk 16 is secured to the tube 4.- and forms a closure for the inner-face of thewheel 11, its edge being turnedfinwardly at 17 to provide a flange.

The wheel 10 is hollow or cup shaped and yha-s'a sleeve 18 rigidly secured thereto and also rigidly secured to the shaft 9, so that the two wheels 10 and 11 turn together.

A speed increasing gearing is interposed between the spring rotated member 7 and the hollow winding and propelling wheel 10. This speed increasing gearing', in this instance, embodies a flange v19 secured to the spring rotated member or sleeve 7 within the wheel 10 and having a stub shaft 2O supported thereon. This stub shaft acts to supv port a pinion 21 which meshes with a gear 22 formed on the sleeve 18. The pinion 21 meshesalso lwith an annular internal gear 23 and is supported by a ring 24, the latterbeing liournalled'between two flanges 25 and 26 secured to the stationary sleeve4 adjacent the wheel 10. Thering 24 is adapted to turn in one direction relatively Yto the stationary sleeve or tube 4, while in the other direction it is held against turning relatively to the This latter result is eected, in this instance, by providing a ring 24 with a pawl 27 pivoted at 28 to the ring 24 and held by a spring 29 toward the lateral teeth oi` projections V30. formed on the iiange 26. The pawl 27V acts insuch a direction that when the spring 5 turns the springv rotated member 7, the-gear 21 will be revolved about the axis ofthe winding and propelling wheel 10 and will also rotate on the stub shaft 20,

thereby causing the gear 22 to be rotated to rotate Vthe vwheel 10, axle 9 and the wheel 11 in the direction'to propel the toy.

The winding of the spring is effected by directly connecting the wheels 10 and 11 with the spring rotated member. This-is effected, in this instance, by providing teeth or projections 31 on the fiange 19 of the spring rotated member and providing ceni trifugally operated detents 32 on the inner face ofthe wheel 10, these detents being pivoted at 33 and having noses 34a arranged to cooperate with the projections 31. The detents are so weighted that, with the rota tion of the wheel, the weighted portions are thrown outwardly and the nosesV 34C are thrown inwardly so that one of them will lll() engage withA the projection 31 as shown in l l.

Cil

F ig. 3, thus establishingr a direct connection between the Wheel 10 and the spring rotated member 7. lt is `apparent that when the Wheel rotates in the direction for prop/lling` Y' the toy, these detente ride .over the projections Without inalifne any connection there-v with. llllien the detents the pio ject-ions, the anis 2O of the 21 xviii revolve and the gear 22 rota s about such axis 20 the time of such revolution. The toothed connection between the gear 21 and the internalgear SO causes the latter to rotate on the tubular stationary asile 4 on the Winding of the spring, this being permitted bythe pawl 27 riding over the teeth 30, so that the Vspeed increasing gearing is inettec1 tive, ivhen a direct connection is established between the Winding and propelling Wheel and the spring rotated member.

*A governor for the motor is preferably mounted in the hollow Wheel 11 and to this Vend comprises a centrifugal governor consisting of tivo Weighted members 34 and 35, the former being pivoted at 36 and the lat- .ter at 37 to the inner face of the hollow Wheel 11. A link 38 is pivoted at 39 to the Weighted member 34 and at 40 to the Weighted member 35, and a leaf spring 41 secured at 42 to the Wheel 11 acts on the Weighted member to oppose the outward movement ofthe members. The lug 43 extending laterally from the Weight-ed member 34 is adapted to cooperate With theflange 17 on the disk 16 secured to the stationary holloiv axle tube 4. With this arrangement. when the speed ofthe toy increases the Weighted members 34 and 35 are swung outwardly at their free ends against'the action of the spring 41, thus tending to retard the motion of the toy. This is further retarded by the frictional engagement of the spring 41 and the flange 17 of the disk 16.

Each Wheel may have a depressed portion 44 in its periphery and in this depressed portion a rubber tire 45 may be secured.

In the embodiment of the invention shown in Fig. 7 the governor is dispensed with and the spring 5 is arranged in the wheel 11a corresponding with the Wheel 11 in the embodiment shown in Figs. 1 to 6. The spring, in this instance, is of fiat volute form having' one end secured to the flange 17a on the disk 16a rigidly secured to the tubular stationary shaft 4. 'The other end of the spring 5n is secured to the spring rotated member 7 a. The shaft 9a is journalled in the spring rotated member 71 and is connected to the Wheel 11a. Theother parts in this construction are substantially the saine as those illustrated in Figs. 1 to 6.

In order to Windrthe spring of the motor,

Ythe toy is moved back and forth on a suitable surface. 1When moving backwards the spring is Wound, due to the fact that the Vcreasing gearing ineffective. `isiteleased, the spring turns the spring rodeteiits 32 engage the projection 31 and form a direct connection With the spring rotated member 7, the gear 21 causing the annuV1 .r Vgear 23 to turn on the stationary tubular axle 4 and rendering the speed in- When the toy tated member 7 and revolves tne gear 21 which, owing to its meshing with the annular gear 23, the latter being held against turning by the pawl 27, turns the gear and rotates both Wheels 10 and 11. The

speed of rotation of the Wheels is controlled by the centrifugal governor mounted in the Wheel 11. n
